According to the Cisco SD-WAN vEdge Routers Data Sheet1, the Cisco vEdge 5000 router is the only model that offers 20 Gbps of encrypted throughput. The vEdge 5000 router delivers highly secure site-to-site data connectivity to large enterprises, offers interface modularity, and supports up to 4 Network Interface Modules (NIMs)2. The other models of vEdge routers have lower encrypted throughput capacities, as shown in Table 6 of the Ordering Guide for SD-WAN3. The vEdge 1000 router has a maximum encrypted throughput of 1 Gbps, the vEdge 2000 router has a maximum encrypted throughput of 5 Gbps, and the vEdge 100 router has a maximum encrypted throughput of 100 Mbps3.

Cisco ISE is a policy decision point that enables enterprises to ensure compliance, enhance infrastructure security, and streamline service operations. Some features and benefits of Cisco ISE include1:

Zero trust across the network: ISE allows only trusted users and devices access to resources on your network. It also uses intel to automatically identify, classify and profile devices.

Policy and lifecycle management: ISE simplifies the delivery of consistent, highly secure access control across wired, wireless, and VPN connections. It also allows users to add and manage their own devices through self-service portals.

Remote management and deployment: ISE supports cloud-based deployment and management, as well as integration with other Cisco products and third-party solutions.

Site survivability: ISE provides local authentication and authorization services for remote sites, even when the connection to the central ISE server is lost.

Visibility of all devices and their users: ISE can provide data about when a specific device connected to the network, what type of device it is, who is using it, what applications are running on it, and where it is located.

Among these features, two statements are true regarding Cisco ISE:

ISE plays a critical role in SD-Access: SD-Access is a network architecture that uses software-defined networking (SDN) principles to create a secure, scalable, and consistent network fabric. ISE is the policy engine that defines and enforces the network segmentation and access policies for SD-Access2.

ISE can provide data about when a specific device connected to the network: ISE uses a number of probes to collect attributes for all endpoints on the network, and pass them to the Profiler analyzer, where the known endpoints are classified according to their associated policies and identity groups. ISE can also provide historical data about the endpoint connections, such as the time, duration, location, and user of the connection3.

The other three statements are false regarding Cisco ISE:

The major business outcomes of ISE are enhanced user experience and secure VLAN segmentation: ISE provides more than just user experience and VLAN segmentation. It also delivers business outcomes such as improved network performance, reduced operational costs, increased security, and simplified compliance4.

An ISE deployment requires only a Cisco ISE network access control appliance: ISE can be deployed on different platforms, such as physical appliances, virtual machines, or cloud services. An ISE deployment also requires other components, such as network devices, endpoints, and external identity sources5.

Without integration with any other product, ISE can track the actual physical location of a wireless endpoint as it moves: ISE can provide the location information of an endpoint based on the network device that it is connected to, such as the switch port or the wireless access point. However, to track the actual physical location of a wireless endpoint as it moves, ISE needs to integrate with other products, such as Cisco DNA Center, Cisco Connected Mobile Experiences (CMX), or Cisco Wireless LAN Controller (WLC)6.

The overall health page of the assurance component in the Cisco DNA Center displays two primary categories: Client and Network1. The Client category shows the health score of all the wired and wireless clients connected to the network, along with the number of clients, the top issues affecting the clients, and the distribution of clients by type, OS, and SSID1. The Network category shows the health score of all the network devices, such as switches, routers, wireless controllers, and access points, along with the number of devices, the top issues affecting the devices, and the distribution of devices by site, family, and role1.

The other options are not primary categories on the overall health page. Server is not a category, but a type of client that can be filtered in the Client category1. Access-Distribution and Core are not categories, but roles of network devices that can be filtered in the Network category1. Wired is not a category, but a subcategory of the Client category that shows the health score of the wired clients only1.

 Cisco ISE benefits our customers by providing network access control and helping them stop and contain real-time threats. Network access control is the ability to enforce policies on who and what can access the network, based on the identity and context of users, devices, and applications. Cisco ISE allows customers to authenticate, authorize, and audit network access, as well as to segment and isolate network traffic based on security and compliance requirements. Cisco ISE also helps customers stop and contain real-time threats by leveraging intel from across the network and security ecosystem, and by automating threat response actions. Cisco ISE can integrate with various security solutions, such as Cisco Stealthwatch, Cisco Firepower, and Cisco Umbrella, to detect and mitigate attacks on the network quickly and effectively. References:

 The new operational paradigm is a way of designing, deploying, and managing networks that leverages the power of intent-based networking. Intent-based networking is a network architecture that aligns the network with the business goals and policies, and uses artificial intelligence and automation to translate the intent into network configurations and actions. The new operational paradigm requires three foundational elements:

Fabric: A fabric is a network topology that consists of interconnected nodes that provide a consistent and scalable way of delivering network services and functions. A fabric can span across multiple domains, such as campus, branch, data center, and cloud, and can support multiple protocols, such as IP, Ethernet, MPLS, and VXLAN. A fabric enables the network to operate as a single entity, rather than a collection of disparate devices and links. A fabric also simplifies the network design and management, as it reduces the complexity and variability of the network elements and interfaces.

Assurance: Assurance is the process of continuously monitoring, verifying, and optimizing the network performance and behavior, based on the defined intent and policies. Assurance uses telemetry, analytics, and machine learning to collect and process data from the network devices and applications, and to provide insights and recommendations for network optimization and troubleshooting. Assurance also enables the network to self-heal and self-optimize, by applying corrective actions and adjustments to the network configurations and policies, based on the feedback loop from the data and analytics.

Policy-based automated provisioning of network: Policy-based automated provisioning of network is the process of applying the intent and policies to the network devices and services, using automation and orchestration tools. Policy-based automated provisioning of network abstracts the network complexity and heterogeneity, and allows the network operators to define the network requirements and outcomes in a high-level and declarative way, rather than specifying the low-level and imperative commands and parameters. Policy-based automated provisioning of network also enables the network to be agile and adaptive, as it can dynamically adjust the network configurations and policies, based on the changing network conditions and business needs.
